Time Query - Please Help?
I’m completely baffled by a query that I thought I had working yesterday, but I can’t get it working today. Here’s the screnario: I’m publishing a story to the web and I don’t won’t it to be published live until: -The current date (type: date) is less or equal to now -The current time (type: time) is less or equal to now So here’s my query: select * from cms_stories WHERE section = 'news' AND published_web_date <= NOW() OR published_web_date IS NULL AND (published_web_time <= NOW() OR published_web_time IS NULL) ORDER BY story_id DESC LIMIT 1 Now the query works for the published_web_date, but not for the published_web_time. It seems to ignore that as you can see from the screenshot returned below from that query.

Limiting Query Time
Is it possible to limit the query time in MySQL (3.x or 4.0)? For example, I'd like to have any query that takes more than a specified number of seconds just quit automatically. Seems dumb, but on a web site, nobody is going to wait minutes for a query to return so they refresh anyway. So on a busy server, MySQL ends up with several queries running that all take a long time to finish which compound to make it even slower. A simple time limit would solve the problem. Yes, I know that the queries should take less time, but again, on a busy server, sometimes the longer queries do take a long time (10 minutes or more) to complete.

Execute Time Of A Query
I'm running a SELECT * query on a table with over 3,000 rows. I need to know the execute time on the query. PHPMyAdmin shows it to me, but because they automatically add a LIMIT 0, 30 I suspect the time is only for those 30 records. It also has a feature to prevent web server timeouts that prevents me from setting the LIMIT to 0, 3100. BTW, I'm programming in PHP. Does the time to run the query get automatically passed when PHP sends the query to MySQL? <? PHP $Query = "select * from my_table where 1"; $Result = MYSQL_QUERY($Query); ?>

Time Query Question
I'm trying to pull dates from a db that are newer than 6 months old. I've been testing with 1 day, since there's nothing in the db that's older than 6 months. query PHP $DATEsql = "SELECT DISTINCT DATE_FORMAT(time_in, '%m/%e/%Y') as time "; $DATEsql .="FROM login "; $DATEaql .="WHERE time_in > CURDATE() - INTERVAL 1 DAY "; $DATEsql .="ORDER BY time DESC "; that is giving me the same results as PHP $DATEsql = "SELECT DISTINCT DATE_FORMAT(time_in, '%m/%e/%Y') as time "; $DATEsql .="FROM login "; $DATEaql .="WHERE time_in < CURDATE() - INTERVAL 1 DAY "; $DATEsql .="ORDER BY time DESC "; This is what I'm interpreting as what I need to do according to the MySql manual.

Query Log With Execution Time?
I have developed a big property portal web site and have probably written about 1000 different SQL queries in the process (OK, maybe only 500 or so) but a lot. The site is now gaining popularity and although it is on a dedicated server I want to make sure that everything is running smoothly. I have optimised several tables with indexes etc. and have sped up certain tasks, but would like to know if there are any other queries that take too long and should be optimised. Is there a way to log all queries together with the time it took to execute the query? Is this already logged and if so - where is it?

Query Execution Time In PHP Script
I am interested in displaying the query execution time as mysql does from the console, but using php. I've looked everywhere for this and can't find anything. Does anyone know how to display this information to the browser via php? The information must be there since the console provides it. I checked the php function mysql_info(), but that only shows records, duplicates, deleted, matches, changed, warnings, etc. Didnt see any specific php function for getting execution time.

Time Zone For Query Browser?
My server time is set to CST. phpMYSQLadmin shows CST. The website that the information is stored on is CST. When I do a query from MySQL Browser, it's providing information back in GMT. Does the browser undo timezone? It makes since on a corporate level, so that the time is always being pulled up correctly. So, my question is. If all my servers and sites are all set to CST, do I still need to do queries with a time zone change in it, CST?

Effect Of Increased Users On Query Time - Rec Specs
I have just started my first big project and I am having trouble predicting the system specs that will be required. At present during trials the site has around 15 users, although this will go to 350 when it is launched. Most of the pages execution time should not scale with the increase in users but there are a few report pages which calculate and order the information entered by the users. Measuring the page on my development machine (Duron 1.2, 768MB PC133, WinXP, running apache 1.3.22, mysql 4.0.15and php4.3.4)... One page I am currently getting 0.2-0.3 seconds. It uses phplib templates and it executes 9 queries at present, 1 of which I predict will scale. It calculates the mean, standard deviation and total of around 90 measures using results from 15 users. I do have a few nightmare pages for the regular users which execute 150+ queries (mixture of selects and updates). Can anyone predict what will happen with 300+ users? I am thinking max load being 20 regular users logged in with 2 users viewing reports. The machine I am currently looking at is P4 2.4, 512DDR with Linux. Will this be suitable?

Time Based Reservation System - Only 1 Query Should Succeed
a user can select a time they want and submit the page * The code selects all the bookings for a range of time. * It then counts how many concurrent bookings there are for each hour. * If there's less than the total (4) it inserts another row ( the user's requested booking ) into the booking table. We also notify people if there has been a cancellation This has led to a situation where a few different people are trying to book the same session at the same time, and succeeding! We've ended up with 5 sessions booked In the course of 2 page requests this seems to happen: User1 - submits their booking site selects to see if there's availability ( there is!) User2 - submits their booking site selects to see if there's availability ( there still is!) site inserts User1's booking site inserts User2's booking

PHP/MySQL Sorting By Date & Time (using Non Military Time)
This is probably a simple issue but I have searched online and can't find an answer. I am using PHP/MySQL and I guess the most intuitive would be to have three select boxes containing HOUR / MINUTE / AM,PM option. Then store the time into mysql using there functions so I can output the data sorting them all by date and time. All the examples I have seen are for military time only but I'm sure there has got to be a simple mysql function or php function that converts non military to military and a formatting function to display with the AM / PM. But I have not found it.

How To Retrieve Mean Time Between Time Stamps
I have a table that stores failure information of external application. The time stamp of every failure event is stored. Now I'd like to make some system performance & reliability statistics calculations based on time stamps in certain recordset; mean time between failure MTBF, down time DT, etc. Example: 2007-09-27 12:23:52 2007-09-27 08:50:23 2007-09-26 23:31:34 2007-09-26 21:45:33 Here the times between are (hours:mins): 3:33, 9:18, 1:46 and MTBF=4:52 Any effective possibility to make this example within a single query - or a procedure is needed?

Date-time Overlaps Another Time
had a time question in mysql... i have a start and end time for a meeting table and i am comparing whether a new meeting conflicts with another meeting in same room on the same date. i was wondering if i could check whether the 'date-time duration' in anyway overlaps another meetings date-time duration. visualized below... ............|____compareToThisMeeting__| .....|_________meetingNewOverlaps__________| i was doing something dumb before i realized i needed soemthing more complex (checking whether the start time of new meeting was 'BETWEEN' the start and end times of a meeting and whether the end time time is as well but i forgot the duration/middle value hehe). (using asp) and just returning booleans with a mySQL SELECT statement is what i am looking for like... //within a loop in asp for meetings on same date/room "SELECT '"+ year+"-"+month +"-"+day +" " + startHourString +":" + startMinuteString +":00''"+ " BETWEEN '"+ thisMeetingStart +"' AND '"+ thisMeetingEnd +"'"; (this doesnt cover the 'middle' overlap areas though)
